Does the interruptor act like a switch? If you hit the switch (whatever it may turn out to be), it moves the platform somewhere. Then when you hit the switch again, it moves it back to original position?

Is the interruptor visible on your layout and can you (or the user) interact directly with it? If so, I would also suggest looking at the MoveTo plugin to move the platform around:c2-plugins-and-behaviors-list_t65170
